8:00 AM
Nice song, chatter Techidiot!
 
GaMeN, as it were.
 
Hey Rubio!
@humn Glad you liked it. That's a very very old one.
 
Nonetheless, challenge me to keep apace.
And I'll challenge the same.
 
Hehe..
 
Anyone who can stumble as many times per second as I deserves recognition.
 
8:06 AM
Are you done with the rest?
 
It just aint' fair!
I woke up in a mess of flu and now I'm busting for embarrassment.
 
Why is that so? :-/
 
Ain't it so. Some of us heal beyond explanation.
 
I'm listening to this ATM, I don't know why
 
Thank you!
 
8:10 AM
May be you are a mod candidate? ;) Nice btw. :)
 
Lovely harmonies.
 
Yes..
 
I would be the most forgiving moderator. And the least reliable.
 
@humn Yep, I'm envious. My brother and I can't do it like that...
 
And, I am listening to Home now which is nicer again..
 
8:13 AM
Which means that you love to sing, @Mithrandir!
 
@humn yep, although I'm not great. I'm working on learning how to read notes so that I can really play piano instead of faking it
 
The best singers fake it.
 
(here we, and the neighbs, go)
 
Lol :D
 
8:15 AM
@humn that's what this guy said - he just improvises
when we asked him what he was doing on the keyboard
 
Think I know what you mean but, zeesh, the link didn't work.
 
?
Yonatan Razel is an American-Israeli singer, writer, composer, musical arranger and conductor. == Background == As a child he learned to play on piano and cello, and studied conducting with Mendi Rodan. With his siblings Aharon, Yehuda and Ricka, the Razels formed a band and performed on Rivka Michaeli's program. Razel's army service was as a musician and arranger for the IDF military band. After his release, he studied conducting and was the conductor for the Israel Chamber Orchestra and the Ra'anana Symphonette. For a number of years Razel abandoned his music, moved to Susya, where he worked...
 
International boundaries.
(trying again)
 
well, Wikipedia should work :P
 
And cello!!!!
(still haven't got a yotube, but it's only a matter of time)
soulful!
 
8:22 AM
Hmm.. Nice! Smooth!
 
I like the tune to Katonti, but the words don't exactly fit
 
I've never heard cello wiggle like that.
(Don't recognize the words, only the tone of voice)
(And I play a little cello)
 
 
(okay, a big cello)
(a music teacher left it in my closet)
 
heh
 
8:29 AM
Sometimes you just can't help toying with what's.
there's an even better one, but youtube hasn't heard of it
 
you are fun!
 
There's a story behind the song..
The girl is getting married and her friend is singing a song for her telling her that he was in love with her..
 
a personal story?
 
She always used to tell the guy that there is no pain in your voice..
Ah no. It's a song from a movie.. We have atleast 3-4 songs in every movie :p
 
8:39 AM
thanks. much as i try i don't honestly understand other languages.
 
Oh yes. It's more difficult to understand the language through a song :)
Look at this -
A typical Bollywood song :D And a much loved one
Check how it starts ;)
 
(catching up)
(almost caught up, nice clusters! and then some)
 
Hehe.. Yeah :)
 
too much for my puter. Time for a reboot. See what happens.
 
These two songs have been stuck in my head for the past week or so... >.<
 
8:52 AM
I've heard the first! Nice. I am liking the others music.. It has an Indian touch..
 
Rough and ready! But I've gotta downgrade. Back, in the best of times.
 
Hello all
 
Is that a head and a raised arm?
 
I think so.
 
8:57 AM
I gesture leaves a bad taste
 
ס_ס
ם_ם
 
You've been staring at your screen for too long
 
well def
 
I see you have a desk?
Is that a mod thing or just a custom chat room?
i.e. anyone could have one
 
anyone
 
9:00 AM
@incesterror21 I've tried a lot of things to break the puzz. But failed to. The new edits are not helping (to me atleast) Curious to know what is going on in there
 
I just created a chatroom.
 
@Techidiot I'm afraid to give away too much
Maybe the puzzle's scope is too unusual
 
@Mithrandir do tell (yes, the puter made good(
 
Yeah. I know that feeling :)
Very thin line between too much and too less.. Hope someone gets it.
 
It's a thin line!
 
9:02 AM
I hope someone else gets it or else I will have to give all my rep to you!
 
@Techidiot I think someone did find "too easy", right?
 
I too found it and ignored it considering it to be just a red herring..Not sure where that fits
 
It is a red herring but also a hint
How did you find it ? By chance?
 
9:08 AM
By using the hint - we are first of all
 
Good, that's how I wanted it.
 
The sweetest humn in the world, can be the meanest humn in the world.
 
Could be a key to steganography ..
 
Now, "too easy" is supposed to tell you that you had the right idea in general
 
@humn as can be?
 
9:10 AM
With the new hint which says "think bigger" it should me more clear I hope.
 
only meant as lyricality
 
I was referencing The Phantom Tollbooth
 
my favorite book!
(not as super crazy about the cartoon, but very appreciative of it nonetheless)
 
cartoon?
 
and, yes, @Mithrandir, one of these days I'll plop a roman-a-clef question at Literature SE.
 
9:14 AM
:D
 
Yeh, there's a cartoon version of the story.
 
*Googles*
 
Race on
 
The Phantom Tollbooth, also known as The Adventures of Milo in the Phantom Tollbooth, is a 1970 live-action/animated film based on Norton Juster's 1961 children's book The Phantom Tollbooth. This film was produced by Chuck Jones at MGM Animation/Visual Arts and stars Butch Patrick as Milo with the voice talents of Mel Blanc, Daws Butler, Candy Candido, Hans Conried, June Foray, Patti Gilbert, Shepard Menken, Cliff Norton, Larry Thor, and Les Tremayne. Jones also directed the film, save for the live action bookends directed by fellow Warner Bros. Cartoons alum Dave Monahan. The film was released...
 
(false alarm)
 
9:16 AM
@incesterror21 Probably the face gives a single letter like "W"
 
You mean the masked face?
 
Yeah.
 
Not sure why you are so obsessed with the masked face.
 
Because it a part of the puzzle body and you have a visual tag :)
 
Fair enough. Although, so far there hasn't been much useful in the body.
 
9:21 AM
The profile pic on the other hand has two white dots which makes me think of braille somehow
I tried adding colors, and didn't found any kind of stego there
 
What else did you check on the profile pic?
 
Looks like letter O
I tried pushing it through some stego decoders
 
Such as? (Never heard of such a thing)
 
link?
 
9:24 AM
thank you
 
I also checked the imgur URL for the icon which is qr4EH
But doesn't lead me anywhere(yet)
The previous ones had some dotted lines on the tongue.. But this new one is clean
 
So why would I feel the need to make it "clean"?
 
To correct or change the hex value may be
 
What are you guys talking about?
 
@Wen1now This
 
9:31 AM
Right on!
 
No niin!
 
I can randomly onebox too :P
 
Comment from some online dictionary: "Right on! - It is how hippies and leftist political activists said "yes" emphatically in the 1970's." @humn Any comments from your side?
 
"Busted"
It was a wonderful time.
 
Right on!
 
Is anybody working on Karst
 
Anyone good at SEDE queries? Out of all the videos posted on TSL, what proportion of them have been within 5 minutes of a comment by Humn?
 
I tried, but I'm not good enough
feel free to outwit me again @Wen1now
 
9:38 AM
I haven't made any solid deuctions yet :(
 
same, I only have a few lines drawn
 
Hey, I don't even have any lines drawn
 
well, for example if you see a 2 2 they must be separated
otherwise they would form a loop
 
That is actually a really good observation
 
(note, not that it applies for this puzzle, but there is an exception if one of them is on a grid edge)
 
9:41 AM
@boboquack I don't think SEDE has chat...
 
I've had some luck with SEDE, @boboquack, but not sure I can explain it. How deep do you want to go? You can pretty much have moderator vision if you want.
 
@Mithrandir oh
Stuck on a different keyboard there?
 
yeah, keep accidentally switching
 
What's SEDE?
 
Data
 
9:42 AM
Stack Exchange Data Explorer
 
SE Data Explorer
 
What's that?
 
There is kinda a way
 
Mith was faster and expanded it all
I'm ashamed of my typing speed
 
9:43 AM
The secret it is to layer SELECT upon SELECT.
 
Are 2s basically 3s in Slitherlink? At least pretty similar, right?
 
! No!
 
yes, 3 of their sides must be lines
 
El'endia Starman has a chat crawler which he used to create TNBDE, so if you ask him nicely you can probably get a working chat searcher for The Sphinx's Lair
 
@boboquack 2s in Karsta relating to 3s in Slitherlink
 
And I though i was being cryptic!
 
@Wen1now Oh I see.
Yes, then
 
(by the way, Wen1now, I apologize for being so caustic once)
 
When was this?
 
Better forgotten!
 
9:47 AM
Do you think 'uniqueness of solution' should be applied to Karst?
 
1
Q: Can you find who am I?

Jeffin I look like boat's top view I am sensitive I was often painted around the edges I am the one who gets beaten most probably on a fight My name is used by a company to revolutionize their industry Make me wet and i will never see you again If you find anything difficul...

 
@ffao Could you explain to me what the numbers mean?
I don't get the explanation
 
so every number is on a polygon
 
A polygon can be triangle, square, ...
 
from the center of each side of that polygon you draw a line going out, and this line stops on a line or on a triangle
 
9:49 AM
Ooh, I found a nice semi-break-in
 
the number of polygons these lines pass through (the "lines of sight"), must be equal to the number
semi-break-in?
 
(sorry @Wen1now, I should be working on you-know-what, but I can't concentrate on it at the moment)
 
Should uniqueness of solution be used?
 
@ffao A deduction that tells us more than something trivial
@Wen1now Ideally, no
In reality, no-one can stop you
 
I would use it if I could, I just don't see anything that would tell me
 
9:52 AM
Those 2x2 squares on the top left and bottom right should be removed... they seem rather pointless
What it tells you is that no line can go through that area... in a vague sort of way
 
@ffao Ohhh, so the 2 close to the center (in the example) hits the line and the corner of the triangle at the same time
And it's worth noting that the initial polygon does also count but only once. Now I get the bottom 4
 
I always forget to count the initial polygon
 
(in this life i'll be manshu, and after that, boboquack)
 
I don't know whether to find that concerning or not.
 
There might not even be enough room.
Take it as a compliment!
 
10:02 AM
SEDE is actually really cool
 
And now you see. No secrets.
Every detail is a puzzle posed.
 
Has anyone done SEDE-golf on PPCG?
 
What's PPCG?
 
@Wen1now The place I'm from :P
 
10:05 AM
Now I want to be you more than ever! (Don't tell manshu.)
 
They wish.
 
Is anybody up for a round of contact?
 
This sort of question is ontopic at PPCG, it's just incredibly rare that anyone writes a good one. (This is a good one, though.) We have the "programming-puzzle" tag for things like this, and it's hardly used, even though "programming puzzles" is part of our name. (I'm beginning to think that we should just let you lot have them; you're better at them.) — ais523 Feb 19 at 1:13
 
I am ~ for about 10-20 minutes, then off.
 
10:10 AM
out of sequence, sorry @Wen1now. I'm game for contact but am losing steam
here we go! speed contact.
(sorry to ask, link?)
 

 Contact

For playing the game Contact, where one person tries to "defend"...
That link?
 
anks!
 
Haha
I love how I was on at midday during the average 'peak' time but there was nobody online
 
Sunday is never peak time
 
Oh, right, it's Sunday there
 
10:39 AM
Bye for now, I'm gonna annoy the neighbs without annoying you as well.
 
@humn the LOTR soundtrack is good
 
hmm, the more I look at this Karst puzzle, the more I think it's going to need some guesswork
 
@Mithrandir , nice
and long!
 
3 and a half hours
 
ahh youtube at yer best
bye again
 
 
1 hour later…
12:00 PM
So, Karst has been giving y'all trouble? :P
 
GaMen, I see I missed a lot of music ;)
 
I could stick more if you want
that last onebox is still playing over here
 
@TheGreatEscaper did you find that solution without guessing?
I could only get here
 
@Mithrandir I've probably listened to that LoTR soundtrack dozens of times
 
@n_palum another two hours left in the video
 
12:05 PM
Yep, no guessing required.
The full solution is coming up.
The breakthrough is SUPER awesome.
Once you find it, the rest of the puzzle is actually not hard.
There's a hint in my solved pic as to what the breakthrough is (take a look at them curves!)
 
I'm actually not experienced in these kinds of puzzles at all
I didn't even know about the adjacent 3s
I filled those in after seeing your answer
 
I'd like to say that I'm not experienced either, but I think most of PSE would disagree with this statement.
 
12:25 PM
@TheGreatEscaper I wanted to solve it, but got annoyed trying to do it on a computer. I plan to print it out at some point and solve it by hand
 
12:35 PM
The breakthrough is AWESOME.
The rest of the puzzle falls apart completely using really standard/trivial techniques after that.
 
12:50 PM
Full(ish?) solution is up.
Detailed breakdown of the key deduction.
The rest of the puzzle is easily cracked using basic deductions i outline.
 
1:33 PM
Why was that last one deleted?
 
The question or the message?
 
@Forklift Because the question was deleted.
 
The message, because the question was deleted. The question, because the user account was deleted.
 
AcK, not again
 
It's a funny question, though
 
1:35 PM
yeah, I mean... that was my question :)
I thought it was a decent puzzle
 
I first saw it on Facebook, with fruit or something for the letters, and exactly the same clickbaity "so-many-percent can't solve this" intro.
And the joke is that (1) it does have a solution but (2) all solutions have at least something like 20 digits in each of the numbers, and solving it requires genuinely advanced mathematics.
 
Yeah, I've seen it too. I think it was made up by some people on Reddit's /r/math (or maybe /r/badmathematics? I can't remember) as a joke.
 
but the one I saw on Facebook didn't have any restriction on the fruits, so you could just say they were some irrational numbers
 
haha, nice. it looked fun, but I was actually kind of annoyed by the text so I passed on it, but I wanted to stick around for the solution
 
@ffao Oh, that's a shame. The version I saw did specify positive integers.
 
1:37 PM
from what I remember of the paper, they didn't show that the 20-digit solution was the smallest possible
 
"Annoyed by the text" - yes, that is pretty common.
 
but the fact that they could only find 20-digit solutions says something
 
well thanks for the explanation. saved me some stress today :)
 
I vaguely thought it was known that the smallest solutions are that big (it might actually be 80 digits, now I think about it), but I'm not sure how to go about finding it again...
 
Too much math
 
1:41 PM
well, I found this mathoverflow.net/questions/227713/… which indeed says only "here are the smallest solutions I found". Perhaps that's all there is, in which case @ffao is right
ah, someone says "The given solution is really the smallest (positive) one. The next larger one has numbers of 167 to 168 digits." but gives no details of how he knows.
 
he does, actually
You use a computer algebra system like Magma or Sage to find the generators of the group E′4(Q) (compare my answer), then you enumerate the points on the non-identity component by increasing height and check if they give positive a,b,c. The numbers a,b,c given in the question come from the first set of six points one finds in this way
 
ah, OK.
 
so that is actually the smallest solution? wow
 
also, the paper referenced in another answer gives minimum solution sizes
for rhs=4 and for various other RHS values
e.g., if we say =38 instead of =4 then apparently the smallest solution has numbers about 1,500,000 digits long
 
clearly, my memory is worse than that of a goldfish
 
1:46 PM
and if we say =178 then it's more like 400 million digits
 
=896 is 2 trillion

Does anyone know if spaces are included in the character limit of 30'000 ?
 
@BeastlyGerbil Spaces count as characters in almost everything with a limit, so I'd assume so
 
probably
 
e.g Twitter's cap limit includes spaces
 
oooh thats bad
 
@BeastlyGerbil Most likely the limit is for the textbox itself and as such is counting all the characters within it. (I doubt they're using a .Trim function of any kind on the count)
 
7:10 PM
I wonder if things like <pre> and > are counted...
I seriously hope not
 
probably
 
'The maximum length of a post, question or answer, on Stack Overflow is 30,000 characters. This includes markdown and any other formatting.' DAMNIT!!!
 
I imagine that's the max size of whatever DB column they're stored in
 
okay well I can save a couple of hundred by replacing <pre> and </pre> with ``
 
I tried to add spaces below an image and it didn't let me post the question
Not enough chars
 
7:12 PM
oh ok...
 
I think they change multiple spaces in a row into one, and trim starting and ending spaces.
 
I think the puzzle body does not count spaces .. Not sure but that's what I remember
 
@Deusovi They do that, but they wouldn't remove all spaces when counting characters
 
Right. But if you had three spaces in a row, they'd turn it into one
not sure if they do that before or after counting characters
 
probably before, but that command doesn't happen inside a formatted text area, right?
 
7:14 PM
I'm sure it's before the character count. would be kind of silly to count them against you and only then remove them
 
You're right, it doesn't
